[solved] ip link set device up seems not working

natch · 2015-04-01 17:16:10

Hi all,
It's my first Arch Linux installation, firstly I would to thanks the community, the wiki was really useful for me !

I'm trying to set up my wifi connection (rtl8723be device),
the driver seems to be OK
I've installed networkmanager

But I can't see any wifi device in networkmanager's GUI...

So I tried :

$ sudo ip link set wlp2s0 up

but wlp2s0 is not switching on :

3: wlp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT group default qlen 1000
    link/ether b0:10:41:df:66:23 brd ff:ff:ff:ff:ff:ff

What could I have missed ?

The command in question did work:

ip wrote:

<NO-CARRIER,BROADCAST,MULTICAST,UP>

The bolded "up" in the angled brackets is what `ip link set` changes. The DOWN after that indicates that even though the interface is up, there is no active connection.

As to what the problem is with network manager, I have no idea - I don't use it. But the most likely suspect is almost always that there are multiple networking services competing. So first, disable all networking services (check the output of `sysmtctl list-units`). Then you can follow the remainer of the manual connection steps in the wiki. If/when that is working, then we'll know your hardware and drivers are all set - then you can chose and configure a management service like networkmanager.

Thanks, I read that part too fast
So... I've removed network-manager properly with pacman

I'm now trying to configure my wifi connection with the "wifi-menu"
but I encountered an error... I'm searching what can be wrong...

Please post the output of:

ls -l /etc/systemd/system/multi-user.target.wants

What steps did you take? It looks like you created a network profile with wifi-menu and enabled it for systemd. Disable the profile, delete the corresponding file and try connecting again with wifi-menu without enabling the new profile. Can you get a connection?

network-manager was not totally removed, I did it
after rebooting, wifi-menu runs without problem
and I'm now connected using netctl

Thanks all
I think, this topic is the "all time noobies' noob topic" !

I'm glad it's working natch. You may want to read up on how to use systemctl to start/stop enable/disable services. There was no need to uninstall network manager or anything else - you only had to stop/disable it. I suspect you removed it with pacman, but since you never stopped the service, it was still running until you rebooted.
